The Relative Roles of Herbivore- and Pollinator-mediated Selection on the Evolution of Floral Display in the Invasive Plant, Lythrum salicaria
… evolution of plant traits frequently focus on pollinators as the primary drivers of floral trait evolution. However, herbivores can also play a role, and, under some circumstances, may even impose stronger selection on floral display than pollinators. This is especially true when the traits …

Resource competition and soft selection in Sabatia angularis
… in turn are an important driver of natural selection, setting the stage for eco-evo feedbacks. Such feedbacks are likely when the competitive neighborhood individuals experience are heterogeneous and individual fitness is dependent on the competitive neighborhood within which it finds …

Silene otites (Caryophyllaceae): Attraction of nectar-seeking mosquitoes to inflorescence odours, and temporal variation of flower scent and flower visitors
… in which mosquitoes have been described as pollinators. In several investigations flower odours were described as effective attractants for mosquitoes, however, in none of the studies the compounds responsible for attraction were identified. Therefore, in the present study the aim was to …

Taxonomical use of floral scent data in apomictic taxa of Hieracium and Sorbus derived from hybridization
… the ecological function of scent components for pollinator attraction, to study their geographical variability or their evolution. In contrast, profiles of inflorescence scent compounds were rarely used for phylogenetic analyses and taxonomy. So far no investigations are available that focus on …
